Question about Hitachi CP-X885 Multimedia Projector

Projector looses rgb signal

Our projector continually looses the rgb signal from the computer. The video returns as soon as the rgb button is selected. This may happen several times in a short period of time or it may wait for an hour or so before the video goes off.

Will not regonize computer source


The projector looks for Horizontal sync & Vertical sync signals from the VGA source. If it finds these signals only then the source is connected. Even if the sync signals are found, the RGB switching should be working. Either there is a problem in sync circuitry or RGB switching. You need to be well conversant with the circuitry.

The projector doesn't recognize the computer RGB signal however it works well with the Video signal


Have you the right configuration?
If, for instance, the PC is set to 1280 X 800 and your projector is set to 800 X 600 then it will not work properly.
Hope that helps.

I have a Hitachi CP-L500 LCD projector. It is connected to my laptop from the svga projector port to the svga port on the the laptop. It is making no signal connection. I have made sure the input button...


I am not familiar with your Hitachi LCD projector . However , I do have a little knowledge regarding video signals and inputs / outputs as well as connections . If your connecting cable is one piece (has no adapters added to either end of it ) I would believe your problem is simply a settings misconfiguration in your projector / computer , or both . First , access your startup BIOS / CMOS settings during the initial booting sequence in your computer by pressing F1 or whichever keys you press when you turn the computer on to access it . Then , in the advanced list , check your primary video input selection to be sure it is default. Then, once the computer is completely booted and you can click on your start selection , go to your video settings and check how to switch between internal and external display options . I say this because it is important that you are able to reroute your video signal to your SVGA Out from the laptop (for sure) and it is in fact in that video output mode. Once you're sure you have a signal going out of laptop through that port , go to your projector video input selections menu and select each and every input option available until the signal comes through . This will only work if you're absolutely 100% sure that your video signal is in fact leaving the laptop via the SVGA port connection .

Why does my projection look green if the colors are right on the computer?


I'm going to guess that you are using an RGB cable to connect to the projector and the projector is expecting a composite signal. The composite signal would be what uses a yellow connector when you use hte red/whjite/yellow type of cable. All of the video is carried by the yellow. If the projector is expecting this and you send out component (RBG in this case), then the only video signal processed is the green. Since the green also contains the sync signal, the picture will be seen but green.

Check the menus on the projector. You should find a video selection area that will allow you to change to component input.

Please update this if you have any more questions.

Projector will not detect a Dell computer


Computers do not generally send an RGB signal, you should be connected via a VGA cable between the projector and the computer. The input menu on the projector should be set to VGA. The output of the computer should be equal or lower to the maximum resolution of the projector.

Projector takes 30-40 min to recognize signal from elmo 110xg


the resolution might not match from presenter to projector. are you using rgb, composite or s-video? the signal might not match. there might be an auto adjust on the projector to read and match the elmo's resolution. if not, the elmo may have an issue sending a powerful enough signal to the projector, and need a new main board.

Power Point Presentation Using Sanyo Pro Xtra X Multiverse Projector


Don't forget to select the Fn key and F4 on HP laptops. It could also be the Fn key and F8 depending on the laptop brand. It is the apple key and the F7 key on a Mac notebook. On Laptops this will toggle the video to the aux port where the monitor cable connects to the projector. There are 3 modes. video on the laptop screen, video on the laptop and projector, or video to the projector only.
